Capacitive Touchscreen Panel. In 1965 EA Johnson described in Electronics Letters a method for using capacitive touchsensing to make a touchsensitive screen a system that would be used for airtraffic control in the UK until the late 1990’s [4] From the late 60’s onwards touchscreens became more and more refined as research continued.

PDF fileCapacitiveTouchScreen Capacitive touch screens applied to a TFT (Thin Film Transistor) or OLED (Organic Light Emitting Diode) offer higher clarity than the resistive method and are not affected by the outside elements The capacitive touch screen panel is one which is coated with a thin material which stores electrical charges like a capacitor.
The capacitive touch panel is used since 1983 It was etched onto the top watch glass surface Case in point Apple put it onto the smartphone that changes our lives totally iPhone development Image source wwwapplecom Basically the capacitive touch panel contains three layers and each layer needs substrate glass as a base.

We now have a superfancy capacitive touch screen version of this shield Instead of a resistive controller that needs calibration and pressing down the capacitive has a hard glass cover and can be used with a gentle fingertip It is a singletouch capacitive screen only! The capacitive touch screen controller communicates over I2C which uses two hardwire pins.
